  • the present invention relates generally to quick connector assemblies. More specifically, the present invention teaches a fluid quick connector incorporating Graphene or Graphene Derivatives for reducing oxygen and water permeation through the coolant quick connector and also includes an integrated latch that eliminates the need for a separate latch component.
  • the quick connector system typically includes each of a male end form and a mating female quick connector end form.
  • the female quick connector internal design is such that the male end form fits or seats into it, creating a strong leak tight connection.
  • a stainless-steel latch typically forms part of the female portion of the quick connector system, which is used keep the two halves of the quick connector system together while maintaining compression on the seal resulting in a leak-tight joint.
  • coolant quick connector bodies are typically made from a Polyamide (PA 66) + Glass Fiber reinforcement.
  • PA 66 Polyamide
  • Glass Fiber reinforcement This material selection has met the needs for the coolant system up to now.
  • One of the challenges with the current material selection for cooling systems is that oxygen and water molecules permeate through the plastic materials. Over time this can result in a volume reduction of liquid in the coolant system and a reduction in a desired 50/50 water to Glycol ratio in the liquid coolant, resulting in less-than-optimal cooling performance of the battery system.
  • the present invention teaches a fluid quick connector incorporating an integrated latch into the engaging male and female end forms and which includes Graphene or Graphene Derivatives for reducing oxygen and water permeation through the coolant quick connector. This arrangement reduces the coolant volume loss and maintains the ideal 50/50 water to Glycol ratio. Additionally, the integrated latch eliminates the need for a separate latch component.

  • Additional steps include folding the latches to a closed position prior to assembly, upon which the male end form is aligned with an open end of the female end form and is relatively inserted toward an interior of the female end form in an axial direction.
  • Other steps include forming an angled exterior ramp upon the male end form for co-acting against and outwardly deflecting the female end form, along with the latches, the latches subsequently seating between exterior annular ledges formed in the male end form in order to establish a fluid-tight connection.

Abstract

L'invention concerne un raccord rapide de fluide 10 incorporant du graphène ou des dérivés de graphène en prise dans des formes d'extrémité mâle 12 et femelle 14 mises en prise qui réduit la perméation d'oxygène et d'eau à travers le raccord rapide de liquide de refroidissement et comprend un verrou intégré 46, 48 qui élimine la nécessité d'un composant de verrou séparé. Un dispositif de retenue intégré 70 est situé au sein de l'interface intérieure d'accouplement de la forme d'extrémité femelle 14 et à l'opposé de l'interface extérieure de la forme d'extrémité mâle 12 et, en combinaison avec un composant de joint torique en EPDM 76, fournit un raccordement d'étanchéité fluidique entre les formes d'extrémité qui réduit la perméation d'oxygène et d'eau à travers le corps ainsi que la perte de volume de liquide de refroidissement de façon à maintenir un rapport eau/glycol idéal (typiquement 50/50).
